In this episode Johnny and the guys tackle the somewhat confusing topic of cell swelling and what role, if any, it plays in the adaptation from BFR exercise application. They discuss why the cell might swell, what the literature has shown thus far, what are the short comings of the existing literature, and how one might incorporate this principle in an optimal fashion in practice.
